As mentioned previously, repositories and archives of datasets are increasingly becoming a mandatory part of research. Bringing with them opportunities for data sharing and secondary analysis alongside demands of ethical care of datasets and issues of confidentiality, anonymity and reinterpretation of findings.

The following resources are by no means exhaustive so if there are archives and repositories you have used to store or share your own work or undertake secondary analysis of other people’s data then please add them in the comments. Particularly if you are working in low income countries or countries not usually covered in data sharing projects.

You might use these in teaching, to practice data analysis, to inform work you are already undertaking, to set baselines for your studies or cross country comparisons, or as a means of re-interrogating existing datasets with new lenses or hypotheses.
